of HopUtis milhauseri, caught at one of the acetylene lamps 

 outside the hotel at Aigle, and a beautiful fresh Plusia v-arfien- 

 teiun which flew into my bedroom at the Eiffel Alp attracted by 

 the electric light. Of larvae found the most interesting was 

 a nearly full-fed larva of Parnassius mnemosyne, which was 

 walking" across the road close to Bex Station ; it fed up slowly 

 on a species of monkshood, and is now a seemingly healthy 

 pupa. 



THE DEAGONFLIES OF EPPING FOREST IN 1905. 

 By F. W. and H. Campion. 



On May 7tli we started up from the rushes a single imma- 

 ture Agrionid, which unfortunately escaped us. Cloud and rain 

 subsequently coinciding with our opportunities for collecting pre- 

 vented the resumption of work until May 28th, when we found 

 that Agrion -puella and Ischnura elegans had already appeared, as 

 well as Pyrrhosoma nymphula, which with us always precedes 

 in point of time the two mentioned species. 



The only addition made during the season to our local list of 

 Odonata was the orange variety of Ischnura elegans, which we 

 shall have occasion to mention again. 



The various species taken were as follows : — 



(1) Pyrrhosoma nymphula, which was very abundant and 

 flying in pairs on May 28th, was not taken later than July 2nd. 



(2) Agrion puella was scarce on May 28th, but common and 

 in cop. on June 4th ; thereafter it was collected regularly until 

 July 30th. 



(3) Ischnura elegans. — Although the species was represented 

 on May 28th by var. rufescens, we did not take the typical form 

 before June -Ith, when it was common. On August 13th, after 

 several weeks during which none but mature individuals were 

 obtained, we suddenly found a considerable number of imma- 

 ture specimens. The last examples of the species were taken 

 on September 3rd. 



Var. rufescens. — As already stated, this variety was met with 

 for the first time in Epping Forest. This fact is somewhat 

 remarkable, as one at least of the ponds at which it has now 

 occurred has been regularly examined for Odonata during several 

 years past, without a trace of it having been found. One 

 specimen was taken on May 28th, one on June 13th, and two on 

 July 16th ; one of those taken on July 16th escaped from the net. 



Var. infuscans has again occurred, and some further observa- 

 tions upon the variety have been published (Entom. xxxviii. 298). 



(4) Anax imperator was seen on a few occasions, but only one 

 specimen was obtained. That was a male, which we found on
